try on your machine
The sysctl command is used to view, configure, and control various kernel parameters in a Linux system. In this case, sysctl fs.file-nr is a command used to query the current file descriptor usage statistics of the operating system.
The fs.file-nr parameter, when read, provides three numbers separated by slashes. These numbers represent:
- The number of allocated file descriptors (open file handles).
- The number of allocated but unused file descriptors.
- The system-wide maximum number of file descriptors that can be allocated.
By executing sysctl fs.file-nr, you will get the current status of these file descriptor statistics. It helps to monitor and analyze the file descriptor utilization on a Linux system.
